Mammalian in vitro gametogenesis
Science, 2021Reconstituting reproduction in culture Research on in vitro gametogenesis (IVG) aims to reconstitute germ cell development, oogenesis and spermatogenesis, in culture. Saitou and Hayashi review some of the recent developments in mammalian IVG.

Sister chromatid cohesion depends on cohesin, a tripartite complex that forms ring structures to hold sister chromatids together in mitosis and meiosis. Meiocytes feature a multiplicity of distinct cohesin proteins and complexes, some meiosis specific, which serve additional functions such as supporting synapsis of two pairs of sister chromatids and ...

Gametogenesis in Planktonic Foraminifera
Science, 1976Gametogenesis in Globigerinella aequilateralis and Globigerinoides sacculifer in culture is preceded by sinking of the organism and loss of its spines. Hundreds of thousands of flagellated gametes, about 5 micrometers in diameter, are produced within the parent shell and released within a ...

The ubiquitin system in gametogenesis
Molecular and Cellular Endocrinology, 1999Ubiquitin is a ubiquitous and highly conserved protein of 76 amino acid residues, that can be covalently attached to cellular acceptor proteins. The attachment of ubiquitin to target proteins is achieved through a multi-step enzymatic pathway, which involves activities of ubiquitin-activating E1 enzymes, ubiquitin-conjugating E2 enzymes, and ligating ...

Gametogenesis of Plasmodium vinckei
Nature, 1965MANY authors in the past have observed the disappearance of gametocytes of certain blood protozoa as a result of their continuous and prolonged mechanical transmission. This phenomenon was especially studied by Vincke et al.1, Rodhain et al.2, Jadin, Yoeli and Pierreux3, and by Michiels4 in strains of Plasmodium berghei maintained in the laboratory for

Kinetics of the Male Gametogenesis*,**,***
Andrologia, 2009The kinetics of the male gametogenesis during the pregonadal period, prespermatogenesis, and "early" spermatogenesis has been described in detail. Concerning spermatogenesis in the adult individual reference is made to the articles of Courot, Hochereau-de Reviers and Ortavant (1970) and of Clermont (1972).

Monitoring meiosis in gametogenesis
Theriogenology, 1998Meiotic recombination is essential to hold homologous chromosomes together so that they can separate accurately in the formation of gametes, thus preventing fetal loss due to aneuploidy. How do germ cells know when they have finished genetic recombination and that it is time to enter the meiotic division phase, and what are the elements that signal the

1994
The process of microsporogenesis, or pollen development, encompasses all stages from microsporocyte meiosis to maturation of the male gametophyte. Meiosis is described in some detail in another chapter of this volume, and therefore the focus of this chapter will be on postmeiotic events.

Gametogenesis and fertilization
1992Abstract Millipedes have separate sexes. Secondary sexual structures have evolved to a high degree to ensure successful transfer of sperm from males to females. In this chapter, all aspects of reproduction will be covered, from the structure of reproductive organs and gametes, through to mating behaviour, egg laying, and early ...
